A little piece I rewrote to explain procedure call stacks to budding computer
scientists.  The tune is obvious.  (First printed in University of Waterloo's
mathNEWS around 1986.)

All around the dynamic RAM
The processor chased the pointer.
The function stopped to return its result--
Pop! goes the stack frame.

Pointers to parms passed by ref'rence,
A pointer back to the caller.
That's the way procedures work:
Pop! goes the stack frame.
